We propose a detection method of corner outlier artifacts and a simple and effective filter in order to remove the artifacts in highly compressed video. We detect the corner outlier artifacts based on the direction of edges going through a block corner and the properties of blocks around the edges. Based on the detection results, we remove the stair-shaped discontinuities, i.e., corner outlier ...
Corner detection or the more general terminology interest point detection is an approach used within computer vision systems to extract certain kinds of features and infer the contents of an image. Corner detection is frequently used in motion detection, image matching, tracking, image mosaicing, panorama stitching, 3D modelling and object recognition. It is difficult to detect both fine and co...
An image stitching is a method of combining multiple overlapping images of the same scene into a larger image without loss of information. Literature shows the use of various corner detection algorithms in image stitching. The most widely used are Harris corner detection method and SIFTS (Scale Invariant Feature Transform) method. In this paper, a comparative study is done forHarris corner dete...
UNLABELLED BACKGROUND To determine the characteristics of clinical care offered to type 1 diabetic patients across the four distinct regions of Brazil, with geographic and contrasting socioeconomic differences. Glycemic control, prevalence of cardiovascular risk factors, screening for chronic complications and the frequency that the recommended treatment goals were met using the American Dia...
Sustainable water resource management requires dams operations that provide environmental flow to support the downstream riverine ecosystem. However, relatively little is known about the hydrologic impact of small and medium dams in the smaller basin in China. Flow duration curve, indicators of hydrologic alteration andrange of variability approach were coupled in this study to evaluate the pre...
Among the countries that can be classified as Near East Africa, North West Africa, and Western Africa, there is a great diversity of foods and dietary patterns. Prevalence of undernourishment as defined by FAO using dietary energy supply data, varies dramatically among these countries, with Tunisia in the lowest prevalence category (<2.5%), and Sierra Leone in the highest prevalence category (>...
Considering the limitations related to the landslide monitoring by Interferometric Synthetic Aperture Radar (InSAR) technique, the method of integration of Globe Positioning System (GPS) with Corner Reflector Interferometric SAR (CR-InSAR) techniques is proposed in this paper. Firstly, deformation in radar line-of-slight (LOS) direction is optimized by introducing the GPS-measured height and at...
An iterative algorithm for the detection of corner points on a digital curve is presented. T h e algorithm does not require any input parameters and yields intuitively appealing results for pictures varying in size and orientation. We first calculate the changes in curvature over a supporting arc whose lengtli is either a fraction of the perimeter or given by tlie subarc bordered by two previou...
We located the aftershocks of the 4 February 1975 Haicheng, China, aftershock sequence using an arrival time difference (ATD) simultaneous inversion method for determining the near-source (in situ) velocity and the location of the aftershocks with respect to a master event. The aftershocks define a diffuse zone, 70 km x 25 kin, trending west-northwest, perpendicular to the major structural tren...
